Background: Several studies confirm higher prevalence of vitamin D insufficiency or deficiency in psychiatric patients.
The incidence is highest in schizophrenic patients. However, up to this date, it is not conclusive that vitamin D deficiency is a cause or effect of psychiatric illnesses. In addition to a few commonly known contributing factors for vitamin D deficiency in general population such as inadequate sun exposure and poor nutritional intake, some of anti-psychotic medications are known to interfere with intrinsic vitamin D synthesis.

Objective: The objective of this study is to identify the prevalence and metabolic association of vitamin D deficiency in urban psychiatric population.

Method: This is a cross-sectional analysis of 108 psychiatric patients in an urban municipal hospital in Brooklyn, New York.
Vitamin D levels were obtained to assess the prevalence of vitamin D deficiency and insufficiency and to examine the association of such deficiency on other metabolic parameters.

Result: Mean age (±SD) was 41.0 (±14.2) and mean BMI (±SD) was 28.2 (± 7.4).
Among the entire study population,

  • 70% had vitamin D deficiency (25 OH vitamin D < 20 ng/ml) and
  • 99% had vitamin D insufficiency (25 OH vitamin D < 30 ng/ml).

There was no significant difference in age, gender, BMI, blood pressure, HbA1c, fasting blood glucose, creatinine, calcium, and TSH in patients with vitamin D deficiency when compared to patients with normal vitamin D values.

Conclusion: Vitamin D deficiency is highly prevalent in urban psychiatry population. Implications of such deficiency on clinical metabolic parameters are largely unclear.
